Africa: widespread from the middle and lower Zambezi south to the Pongolo system (Ref. 7248). Also known from the Luachimo River (middle Congo River basin) in Angola (Ref. 11970). Reported as Labeobarbus cf. marequensis from the lower Congo (Ref. 94750); needs confirmation.

Max length : 47.0 cm TL male/unsexed; (Ref. 7248); max. published weight: 6.0 kg (Ref. 7248)

Short description Morphology | Morphometrics

Biology     Glossary (e.g. epibenthic)

Prefers flowing waters of perennial rivers. Uncommon in dams. Feeds on a wide variety of food items, primarily algae and aquatic insect larvae; also takes small fishes, snails, freshwater mussels and drifting organisms such as beetles and ants. Breeds in spring and summer, migrating upstream in rain swollen rivers to spawn in rapids. Males mature at 70 cm FL, females mature at 28 cm FL. Occurs with the small-scale yellowfish in many Transvaal rivers (Ref. 7248).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00360 - 0.01393), b=3.00 (2.83 - 3.17), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.44 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100) .
